Oracle vs SQL Server vs MySQL Contest!
As you study databases, there is a category of databases known as relational databases. These organize data in tables. The three most popular relational databases are MySQL, SQL Server, and Oracle. These database systems are top competitors. These are very similar and they are all very popular. Which one is best? They are very strong competitors. Of course certain ones are better for certain things, but they are all based off of the SQL standard. I am announcing that I am making videos over all three relational database systems. I am uploading them at the same time and turning it into a competition. The scoring systems works like this: 1 view = 1 point. 1 like = 10 points. The competition starts on video #23 and ends on video #150. After this I will add up the points and see which series wins. The winning series gets a bonus 50 videos. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ HELP ME! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://eepurl.com/-8qtH Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - https://www.dreamhost.com/r.cgi?1487063 (The best web hosting for a cheap price!)

Oracle DB Vs MySQL for Enterprise DataBase Deployments
Oracle DB is big, and expensive, but it brings a lot to the "table" when compared with MySQL. MySQL has limited ability to audit. MySQL's security is unsophisticated. There are no groups or roles, no ability to deny a privilege (you can only grant privileges). A user who logs in with the same username and password from different network addresses may be treated as a completely separate user. There is no built-in encryption comparable to Oracle. MySQL's Authentication is built-in. There is no LDAP, Active Directory, or other external authentication capability. MySQL has no MPP (massively parallel processing ) support. Unlike Oracle MySQL has no fractional-second storage type for times, dates, or intervals. There is no RAC (Real Application Cluster) support in My SQL, and no failover or server promotion either. These are strong features in Oracle MySQL's number of joins per query is limited to 61. Oracle's limit is much larger. MySQL Replication is asynchronous and has many limitations and edge cases. For example, it is single-threaded, so a powerful slave can find it hard to replicate fast enough to keep up with a less powerful master.

Should I Learn Oracle or MySQL?
Should I learn Oracle or MySQL? MySQL is a popular open source database, but Oracle seems like the default database I see in use. Oracle is more expensive to implement and to train in. The certifications are like Microsoft's examinations, in that the classes and tests cost more. Then I need to go with MySQL. Not so fast. Popular should equal more job opportunities. MySQL has stronger database authentication based on the person's location. However, Oracle has corporate support to assist you with any problems you have. Which database do you think is better? Oracle does have a number of superior database management tools like rman, dataguard, internal job scheduling and queues. Oracle also has a more mature stored procedure language compared to MySQL. Stored procedures make it a lot easier to add verification logic and corrections to your database, instead of reprogramming the application that relies on the database. MySQL originally didn't have stored procedures or the rich programming environment Oracle did. However, MySQL is catching up. I know that a lot of companies like Oracle's hot backups so that restorations are faster in case of database failure, and the Real Application Clusters that lets your users search several servers at once is a good value. All of that is why Oracle is so often used, especially by big companies. Where is MySQL used? MySQL is free to a lot of non-profits and non-commercial groups. So it is popular at small charities and schools. It sounds like I need to learn Oracle just to gain access to the higher paying jobs, since non-profits don't pay much. Or you could learn Microsoft SQL. I'm not that desperate. Oh, come on. You could manage Microsoft databases on Microsoft Windows servers if you learn Microsoft SQL. I'd rather work for minimum wage at a non-profit with MySQL than MSSQL.

Oracle SQL Tutorial 1 - Intro to Oracle Database
As illustrated in the video, Oracle Database is a program designed to hold lots of information, or data. There are all kinds of different databases and they all have their uses. Some of the most common ones are MySQL, SQL Server, Sybase, and MongoDB. All of these have different uses. The differences will be easier to understand after you learn more about each kind of database. We did not discuss it much in the video, but if you are wondering what “SQL” means in the title, it stands for structured query language. Structured query language is a human readable computer language that is used to tell databases to do things. We will discuss SQL and Oracle SQL Developer more in future videos. Databases are better than spreadsheets because they allow multiple users at one time, different levels of access given to users, recovery options and transactions, and it is more protected from hacking and malicious destruction. Programming languages often have very useful functions or methods that can be used to communicate to a database and therefore they are a naturally good option for the back end of programs. This course will go over all of the major parts of database programming using Oracle SQL. We will be using Oracle 11g, but these videos should still work with other versions, including the most recent 12c. Q and A ~~~~~~ How much does Oracle cost? The full enterprise edition costs thousands. They have other versions for less and they even have a FREE VERSION! This is known as the XE version (eXpress Edition). That is the one we will be using. How long does it take to learn SQL? You can learn all of the basics and be an efficient beginner database developer in only about a month of practice. To become an intermediate it can take anywhere from an additional 3 - 6 months with a only a few hours of studying and practicing each day. How can I learn SQL faster? Take notes and actually mess around with making your own database. Watch these videos until you understand the concepts within them, read articles and books that teach in more depth.

What are the advantages of MySQL as compared with Oracle DB?
Q. What are the advantages of MySQL as compared with Oracle DB? Some of the main advantages of MySQL over Oracle DB are as follows: I. Cost: MySQL is an Open Source and free RDBMS software. Oracle is usually a paid option for RDBMS. II. Space: MySQL uses around 1 MB to run whereas Oracle may need as high as 128 MB to run the database server. III. Flexibility: MySQL can be used to run a small website as well as very large scale systems. Oracle is generally used in medium to large scale systems. IV. Management: In MySQL, database administration is much easier due to self-management features like- automatic space expansion, auto-restart and dynamic configuration changes. In Oracle dedicated DBA has to work on managing the Database. V. Portable: MySQL is easily portable to different hardware and operating system. Migrating Oracle from one platform to another is a tougher task.

Should I Learn SQL Server or MySQL?
Should I learn SQL Server or MySQL? Microsoft's SQL Server has a big market share because it was shipped with MS servers, and it had a good graphical user interface compared to other databases. That's like saying I should learn Microsoft Office because it is on 90% of all computers. Well, 80% today. In the 1990s, SQL Server was one of the best database servers around. Just because it was big in the pre-internet era doesn't mean I should learn it today, except in history class. MySQL is better at handling multiple instances of a database kept on the same machine. MySQL runs on far more platforms, such as Solaris, MacOS and SCO. Where did SCO go? I never hear about it anymore. It's like LISP - only whispered and practiced by a small but dedicated core of devotees. MySQL came out with a pluggable storage engine architecture back in 2008, beating out Windows then and in some areas today. They are both high availability. Both have stored procedures, triggers and distributed processing. MySQL is free, so there are literally millions of instances of it to be supported. And millions of Microsoft SQL Server installations, all of them at companies that can afford Microsoft SQL Server. That implies they can pay an admin well, too. MySQL can run on a Windows machine, Microsoft just doesn't advertise it. icrosoft has built in the functionality to their database. For what you pay for it, it shouldn't need an admin. Conversely, if you have REDCap or another non-Microsoft server package, you already have MySQL because it is built into the tool. Which one is easier to support? Both systems have replication schemes, but MySQL's replication is limited. SQL Server has a lot more reports, but MySQL has minimal reports. So you get what you pay for. You don't have to pay for MySQL. I'll learn the Microsoft SQL Server, since there are more decent paying jobs in it. And you can learn MySQL on your own time, since you can get a practice version for free. Only if it is literally worth my while.

SQL: Delete Vs Truncate Vs Drop
In this tutorial, you'll learn the difference between delete/drop and truncate. PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

R tutorial: connecting to a database
Learn more about connecting to databases with R: https://www.datacamp.com/courses/importing-data-in-r-part-2 Welcome to part two of importing data in R! The previous course dealt with accessing data stored in flat files or excel files. In a professional setting, you'll also encounter data stored in relational databases. In this video, I'll briefly talk about what a relational database is and then I'll explain how you can connect to it. In the next video, I'll explain how you can import data from it! So, what's a relational database? There's no better way to show this than with an example. Take this database, called company. It contains three tables, employees, products and sales. Like a flat file, information is displayed in a table format. The employees table has 5 records and three fields, namely id, name and started_at. The id here serves as a unique key for each row or record. Next, the products table contains the details on four products. We're dealing with data from a telecom company that's selling both with and without a contract. Also here, each product has an identifier. Finally, there's the sales table. It lists what products were sold by who, when and for what price. Notice here that the ids in employee_id and product_id correspond to the ids that you can find in the employees and products table respectively. The third sale for example, was done by the employee with id 6, so Julie. She sold the product with id 9, so the Biz Unlimited contract. These relations make this database very powerful. You only store all necessary information once in nicely separated tables, but can connect the dots between different records to model what's happening. How the data in a relational database is stored and shuffled around when you make adaptations, depends on the so-called database management system, or DBMS you're using. Open-source implementations such as MySQL, postgreSQL and SQLite are very popular, but there are also proprietary implementations such as Oracle Database and Microsoft SQL server. Practically all of these implementations use SQL, or sequel, as the language for querying and maintaining the database. SQL stands for Structured Query Language. Depending on the type of database you want to connect to, you'll have to use different packages. Suppose the company database I introduced before is a MySQL database. This means you'll need the RMySQL package. For postgreSQL you'll need RpostgreSQL, for Oracle, you'll use ROracle and so on. How you interact with the database, so which R functions you use to access and manipulate the database, is specified in another R package called DBI. In more technical terms, DBI is an interface, and RMySQL is the implementation. Let's install the RMySQL package, which automatically installs the DBI package as well. Loading only the DBI package will be enough to get started. The first step is creating a connection to the remote MySQL database. You do this with dbConnect(), as follows. The first argument specifies the driver that you will use to connect to the MySQL database. It sure looks a bit strange, but the MySQL() function from the RMySQL package simply constructs a driver for us that dbConnect can use. Next, you have to specify the database name, where the database is hosted, through which port you want to connect, and finally the credentials to authenticate yourself. This is an actual database that we're hosting, so you can try these commands yourself! The result of the dbConnect call, con, is a DBI connection object. You'll need to pass this object to whatever function you're using to interact with the database. Before we do that, let's get familiar with this connection object in the exercises!

Should I Learn SQL or Access?
Should I learn SQL or Access? SQL is free. Sometimes you get what you pay for. And sometimes what matters is what you can get out of it. SQL does not have data extraction. However, SQL express has an import and export wizard. Why do people promote Microsoft Access for data analytics? Microsoft Access is cheaper than SAS and does just as good a job at mid-level analysis. You get a mini-version of Big Data without spending 20K per license. And you can import and export to Microsoft Excel. There are tools for exporting SQL database entries to Excel, too. I think everything is plug and play with Excel. That's what you get when you have the 800 pound gorilla on the computing block. If you learn Microsoft Access, you'll be learning a tool installed on 80% of all computers. And a lot of hiring managers have heard of it if only because they've seen it above Microsoft Excel and Word. So why would I want to learn SQL? SQL is a key tool in manipulating and maintaining databases. These are databases larger and more complex than anything you can run in Access. Why do so many people hate SQL? SQL was designed before object oriented programming and web apps. And then there's the fact that its queries are more like SAS than Python or Java programming, throwing a lot of programmers in for a loop. That does not tell me why I should learn it. If you want to maintain databases, it is either SQL or Oracle. And since Oracle is so darn expensive, SQL it is for many mid-sized companies and even large ones. There's NoSQL. It is like the un-cola of databases. NoSQL does not have a standard engine or toolset. It has to grow up before it can be considered a proper rival to SQL. So if I want to manage and query databases, it is SQL. Unless you want to be a glorified Microsoft Office expert, yeah.

Detailed Article @ http://www.mytecbits.com/microsoft/sql-server/what-is-dbms-what-is-rdbms My Website: http://www.mytecbits.com DBMS vs RDBMS: a. To Start with, DBMS was introduced during 1960s and RDBMS during 70's. b. DBMS Initially followed the navigational model of data storage, then evolved as network model and hierchical model. c. RDBMS followed the relationship between tables in the form of keys and indexes. d. Because of the navigational model in DBMS, fetching data is slower for complex and large amount of data. e. On the other hand, Data fetching is much faster in RDBMS because of the relationship between tables. f. So, DBMS is used for small applications and RDBMS is used for complex and enterprise applications. g. Data redundancy is very common in DBMS leading to difficulty in maintaining the data. In RDBMS, keys and indexes are used to avoid redundancy. h. Some examples for DBMS are dBase, Microsoft Access, LibreOffice Base and Fox Pro. i. The popular examples of RDBMS are, SQL Server, Oracle, MySQL, MariaDB and SQLite.
